Great Service

Communication was great. Informed the order was placed. Informed when it shipped (next day). Informed the order was out for delivery.

I don't think the ink was dry before the order arrived.

Best prices on breakers although subpanel was a bit more expansive than elsewhere. Really quick shipping, quick support and refund for one of the defective breaker.
